For the purpose of searching novel nano-scale hybrid devices of organicmaterials on Si semiconductor substrates, we fabricated monolayer and multi-layers organic moleculeson chemically modified Si surfaces. The interface structures and their electronic properties have beeninvestigated by using synchrotron radiation spectroscopy, scanning tunneling microscopy, infraredabsorption spectroscopy, photoelectron spectroscopy and 4-probe surface transport measurement.
